FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Hellcat motor 'fits like a glove' in the Wrangler and Gladiator, says Jeep

Just like "technically correct" is the best kind of correct, "technically possible" is the best kind of possible. Specifically, it's technically possible to slot a Hellcat crate motor into the Jeep Wrangler and Gladiator, as confirmed by Jeep brand chief Tim Kuniskis. Speaking to Australian media last week, Kuniskis went on to say that "everybody" keeps asking him if the supercharged, 6.2-liter Hellcat V8 fits in the Wrangler and Gladiator, and that the answer is yes. "It fits like a glove," said Kuniskis. But — there is a but — the fitment is so close for comfort, it makes the combination one that Jeep can never produce. "There's no air space around the engine [...] so you have no crush space, you have nothing that can be used to absorb energy in a crash. It's not a problem to put it in — other than emissions and fuel economy — except it would never pass any crash tests, and that's a problem," as Kuniskis told Drive. However, since the Hellcat is now out of the bag, it's probably only a matter of time until hobbyists with access to these engines will start putting them into Wranglers and Gladiators. And with the time-honored piece of advice — just don't crash into anything — it'd be a combination worth seeing and hearing. Just to throw it out there, a "Hellcrate" engine costs less than $20,000 new. Kuniskis also said that Jeep is "gauging interest" for the J6 concept, one of the Easter Jeep Safari concepts that were just revealed. "[The J6] is just a concept at this stage. But that doesn't mean we're not going to gauge interest for it." However, he said justifying its production is apparently "tough."

Jeep previews Easter Jeep Safari concepts, and one is called Jeepster

Easter is coming up, which is a big deal for both Christians and Jeep fans. The latter of which are excited because the annual Easter Jeep Safari off-road event in Moab is coming, along with Jeep's wild concepts it builds for the event each year. We're getting an sneak peek at two of those Jeeps early, thanks to illustrations the company revealed. The first of them is very obviously a two-door 2018 Wrangler, but with some small changes, and the inspiration is obvious when spotting the badge on the front fender: "Jeepster." This concept pulls from the old Jeepster Commando from the '60s and '70s, a slightly longer Jeep that was a bit more civilized and had an available hardtop that had a distinct slant at the back. The slanted rear roof is very clear on this Wrangler's hardtop, and it has the contrasting color that its inspiration had, too. This Wrangler Jeepster is more off-road ready, though, with big chunky tires, a full-size spare moved inside, and gas cans mounted to the rear cargo door. It's more difficult to tell what sets apart the second Jeep Safari concept. It's obviously based on the 2018 Wrangler. The front fenders have been severely cut down and the front bumper removed to make room for what appear to be enormous tires and lots of suspension travel. It also bears a big hood scoop, maybe indicating a more powerful engine underneath. It also has full front doors, but the rear top has either been removed or lowered. We'll have more details on these and other Jeep Safari concepts in the next couple of weeks around the time of the event. So stay tuned for more wild Jeep news.
